'Love Island' winner makes Kem-eo appearance

Earlier this year, Firecracker made a set of films showing regular people explaining Shell products in terms your granny would understand. The casting brief called for relatable, likeable sorts from all walks of British life: from shopkeepers to personal trainers to (yes) even grannies.

We also had barbers explaining the difference between petrol and diesel (it's the molecular chain lengths, obviously). One of these - an ebullient beatboxer - will now be familiar as Kem, king of Love Island 2017.
